Mateusz Holenko f88b259eba emulator: Use external hw/common.h from LiteX 
Remove code copied from `hw/common.h` and use
the header from the LiteX repository provided
using `LITEX_BASE` environment variable.

Content of `common.h` is now evolving (new functions
are added, some are removed) and syncing it
between repos would be cumbersome.
